No "execute" access on this directory.

In this context "x" means ability to search directory, so this is normal.
Of course, root being root gets to ignore this flag.

To be precise, on a directory the "r" bit allows you to access a file *if*
you know its name, while the "x" bit allows you to list the files in the
directory. Not quite sure what it's used for in practical security
application, but that's the standard protection model.

There's definitely nothing wrong here, this is standard behaviour.
